Learning-by-Doing Approach to Teach Microcontroller Course with Portable Training Board

Microcontroller education is attracting increasing attention owing to the widespread application of microcontroller-based systems. This study proposes the learning-by-doing approach. Rather than emphasizing a deep understanding of datasheets and register-level programming, the new teaching model focuses on microcontroller-based applications. During the pre-class, in-class, and post-class phases, students were instructed to practice writing subroutines or building circuits to interface external devices with a training board. A typical case study is presented to illustrate the detailed process of the proposed model. Feedback from students and teaching supervisors in the recent years has shown that the teaching approach coupled with the training board provides students with more opportunities to work on real equipment, which benefits both the grasp of the theoretical knowledge and improvement of practical skills.

Decision Tree Method for Automation of Plant Sprinklers and Monitoring Based On Soil Moisture

Watering the plants is an important part of plant care, but due to our busy schedules, we frequently forget to do it. It can be caused by a number of variables, including the weather, in addition to human irresponsibility. The goal of this research is to develop a device that can automatically water plants and monitor plants based on soil moisture. Automatic sprinklers that use NodeMCU ESP8266 and Telegram bots employ the decision tree approach. The C 4.5 algorithm is used by the Decision Tree approach to choose the microcontroller's course of action. The value of various case studies utilized in this study is determined using algorithm C 4.5. The Arduino IDE, Fritzing, and Visual Studio Code were the tools used to design and produce this tool. Additionally, it configures Telegram bots using the Telegram universal bot library. The website setting for plant monitoring employs the native PHP language, but the configuration of the telegram bot uses the general telegraph bot library. The end result is an automatic plant sprinkler that operates based on the soil moisture value and activates the water pump when the soil moisture level drops below a threshold of 50%. When the soil moisture reading exceeds 75%, the water pump will then turn off. The outcomes of this investigation also comprise websites and Telegram bots for tracking soil moisture levels.

Enhancing Experiential Learning to Address Loss of Hands-on Laboratory Due to Covid-19 Pandemic

All sectors of life have been hit hard by the pandemic caused by covid-19. This impact has been brutal on streams like engineering in the educational sector, where practical or laboratory courses play a vital role in learning. Due to the limitations of online learning, the students could not explore the full extent of hands-on learning in their Fourth semester ARM microcontroller course. In order to compensate for the loss, the laboratory activities in the Fifth semester RTOS (Real-Time Operating System) Laboratory course are enhanced to provide students with a hands-on learning experience in building applications in both the ARM and RTOS environment. The extended activities enhanced student learning in the ARM environment, which they were previously deprived of during online instruction. Also, emphasis is provided on applying optimization techniques to memory and timing requirements for a given problem statement. The results show that the extended activities helped students co-relate and integrate concepts addressed during their 4th and 5th-semester courses and build a small application of the embedded systems. Keywords—Embedded Real-time systems; Extended Activity; project-based learning;

AbstractToday, microcontrollers are of paramount importance in various aspects of life. They are used for design in many industrial fields from simple to highly complex devices. With a COVID‐19 crisis going on, blending learning is the ideal solution for a post‐pandemic society. This paper proposes a blended learning system as a solution to address today's problem in teaching microcontroller courses through collaboration between distance learning with the proposed training toolkit for real work. Implementation of the proposed solution began by constructing an inexpensive training kit (100$), to empower all students, even those in remote rural areas. The distance learning model allows the simulation of the proposed IoT projects electronically anywhere and at any time using the Proteus design suite, which helps students to conduct them before the actual laboratory appointment. Two learning models are programmed in assembly language which is directly related to the internal architecture of the microcontroller and provides access to all the real capabilities of its central processing unit. To get acquainted with all the features offered by the microcontroller integrated circuit, various IoT projects were constructed, each one dedicated to learning its architecture features, important to engineering students. The proposed IoT systems operate with a minimum consuming power that is very important for portable devices. Questionnaire questions for students were formulated to measure the proposed system benefit over three academic years.

Enriched Blended Learning through Virtual Experience in Microprocessors and Microcontrollers Course

Microprocessors and microcontrollers is a course that demands concurrent delivery of pragmatic and dogmatic approaches to the students in order to ensure effective learning. Online sessions and active learning for such courses pose challenges to both teachers and students, especially during this pandemic period. In order to combat these challenges, and to kindle the interest among the students in learning the course, a new methodology which supports blended learning through virtual experience is presented in this paper. The proposed methodology was implemented for the third year engineering students of circuit branches. This paper highlights the effectiveness of using open source emulating environments like Edsim51 and EMU8086 for providing a virtual laboratory experience to the students. These virtual environment provides a complete visualization of the internal functionality of the microprocessor/microcontroller architecture, and also enhances practical exposure of the students. In order to further augment the students� affinity towards the course, the teacher adopts different pedagogical approaches, which is best suited for ICT based blended learning in the online teaching environment. The assessment of this virtual experience is carried out using different online assessment components such as quizzes, assignments as concept maps/videos shared by the students, mini projects etc. Based on the assessment results, an analysis is carried out and it shows significant improvement in student engagement, in depth understanding of the course and improvement in programming skills of the students. Thus, this experience not only acts as a countermeasure to the lack of real time laboratory sessions but also promotes �understanding by doing�, which seems almost impossible during this pandemic situation.

An Introduction to Soft-Core Processors and a Biomedical Application

Despite the ubiquity of microcontrollers, widespread use of soft-core microprocessors is much less common. Most undergraduate curricula have a digital course involving fieldprogrammable gate array (FPGA) programming, in languages such as VHDL or Verilog, and separately have a microcontroller course that uses the C language. But few synthesize these two topics to involve programming an FPGA to simulate a microcontroller.

Influence of Arduino on the Development of Advanced Microcontrollers Courses

This paper describes the development of courses in the field of digital design that use Arduino boards as their main platforms. Arduino offers an intuitive development environment and multiple hardware and software resources that allow rapid development of microcontroller-based projects.

We propose a methodology that introduces the study of microcontrollers using Arduino to develop different types of projects and proceeds to study the system architecture to gain control on the device. This methodology has been used in an undergraduate course in microcontrollers and a graduate course in advanced techniques in digital design. The students of the microcontrollers course showed improved design skills and motivation compared to the students from previous versions of the course. With respect to the advanced techniques in digital design course, the students were able to take advantage of Arduino platform to gain a deep understanding of hardware/software co-design of embedded systems.
